BENCH-VISE.

SPECIFICATION formingpart of Letters Patent No. 267,986, dated November 21, 1882.

Application filed October IO, 1882. (No model.)

To all whom it may concern:

Be it known that I, THOMAS RENO, of Detroit, county of Wayne, State of Michigan,

have invented a new and useful Improvementin Bench-Vises; and I declare the following Fig. 2 is a rear elevation. Fig. 3 is a separate view of one of the parts.

The object of my invention is to provide novel means whereby the jaws of a vise can be quickly adjustedindependentlyof the usual adjusting-screw.

In carrying out my invention, as shown in the drawings, A and A represent the jaws.

B is any suitable operating-screw, passing through them, provided with the handleor lever B.

(J is the lower slide-bar, rigidly secured in the jaw A, and passing through amortise in the jaw A, said mortise preferably provided with a pulley,'a, beneath the slide-bar. Said slide-bar is also preferably provided with a groove, 0, adapted to receive a chain.

D is a chain or cable of suitable length, secured to the end of the slide-bar, and passing over pulleys a and a through the jaw A, and

secured to the jaw A.

E and E' represent the two portions of a divided nut or collar, rigidly secured upon the armsF and F. Said arms are pivoted at one end to the jaw A or to an intervening plate secured to said jaw.

H is a disk provided with a lever, H, and pivoted to thejaw A or to a plate on thejaw. Said disk is connected with the ends of the arms F and F by means of the connectingbars h and h. These bars are secured eccentrically to the disk, the construction being evident that the chain may be tightened, if

desired.

A vise so constructed may be made either of wood or metal, or of wood faced with metal, as may be preferred. its operation will now. be understood. When it is desired to adjust the jaws, by rotating the disk H in the proper direction the nut or collar E E is opened, al-. lowing the jaw A to be moved freely back and forth upon the sorewB to any desired dis-. tance. Then by rotating said disk in the opposite direction the collar is engaged upon the screw, when by the handle B'the jaws may be tightened as required. It will be seen-that when the jaw A is moved back or forth the chain D will pass over the pulleys a and a and the two jaws willbe'kept parallel thereby.

VVhat'l claimziss V 1. In a bench-vise, the combination, with the jaws and operating-screw, of the pivoted arms F- and F, provided with a divided collar or nut, E E, adapted to engage said screw, and means for opening and closing said arms, substantially as and for the purpose described.

2. The arms F and F, provided with the divided nut or collar E E, adapted to engage the operating-screw of a vise, and means for opening and closing said arms, the construc-' tion being such that the divided nut or collar THOMAS RENO.
